Based on an extensive model intercomparison, we assessed trends in biodiversity and ecosystem services from historical reconstructions and future scenarios of land-use and climate change. During the 20th century, biodiversity declined globally by 2 to 11%, as estimated by a range of indicators. Provisioning ecosystem services increased several fold, and regulating services decreased moderately.

Here, we evaluated the changes in terrestrial biodiversity intactness, expressed by the mean species abundance (MSA) metric, resulting from three of the shared socio-economic pathways (SSPs) combined with different levels of climate change (according to representative concentration pathways [RCPs]): a future oriented towards sustainability (SSP1xRCP2.6), a future determined by a politically divided world (SSP3xRCP6.

- Human consumption significantly contributes to biodiversity loss, with a systematic study quantifying this impact across 45 countries and global regions.
- The research reveals that biodiversity loss per citizen varies greatly by country, often increasing with higher per-capita income, and that food consumption is the leading cause of this loss at an average of 40%.
- Recommendations for policymakers include addressing greenhouse gas emissions and land use strategies in order to effectively protect global biodiversity as populations and incomes rise.
